Details
Custom Machining Component Service
- Machining diameter: Ø0.8 mm ~ Ø51 mm
- Machining tolerance:
- ±0.003 mm for copper and aluminum materials
- ±0.005 mm for other materials.
- Actual tolerances vary by material, part design, and customer requirements. For example, the typical tolerance for a Lock Cylinder is ±0.015 mm.
Why Dimensional Accuracy Matters for Lock Cylinder Components
Lock mechanisms rely on precise interaction between cylinders, pins, and internal moving parts. Even small dimensional variations may affect rotation smoothness, key engagement, and security performance.
Precision machining helps improve:
- Smooth cylinder rotation
- Accurate internal component alignment
- Consistent key operation
- Reduced mechanical friction
Practical examples
- For padlock cylinders, accurate machining of the rotating core helps ensure smooth movement when the correct key is inserted.
- For internal lock pins, consistent dimensions help maintain proper positioning and prevent irregular movement during operation.
Material Selection for CNC Machined Lock Cylinder Components
The material selected for lock cylinder components depends on factors such as wear resistance, machining performance, corrosion resistance, and long-term operating stability.
Other machinable materials, apart from those listed below, are detailed on this page.
Copper (C3604) for Smooth Rotation and Precision Lock Mechanisms
C3604 brass is commonly used for lock cylinder components because of its excellent machinability and stable performance during repeated mechanical movement.
Typical applications include: Padlock cylinders, Lock pins, Internal rotating components, Precision key mechanism parts.
Why it is selected:
- Excellent machinability for small precision features
- Smooth surface characteristics
- Good wear resistance for repeated operation
- Stable dimensional accuracy
For lock systems requiring smooth rotation, accurately machined brass components help maintain consistent interaction between internal parts and improve user operation.
Free-Cutting Steel (SUM24L / 12L14) for Wear-Resistant Lock Parts
Free-cutting steel is commonly used for precision lock components requiring stable machining performance and repeated mechanical operation.
Typical applications include: Lock pins, Rotating shafts, Internal fastening parts.
Why it is selected:
- Excellent machinability
- Suitable for complex small components
- Stable mechanical performance
- Supports additional surface treatments
For security mechanisms with frequent operation cycles, steel components help maintain reliable movement and long-term durability.
Other machining materials can be found on this page for reference.
Surface Finishing for Padlock Cylinders and Lock Components
Lock cylinders operate under repeated rotation and frequent contact with keys. Proper surface finishing helps improve wear resistance, corrosion protection, and long-term operating smoothness.
Common secondary processes include:
- Nickel plating – Improves corrosion resistance while providing a clean, durable finish for brass and steel components.
- Chrome plating – Increases surface hardness and wear resistance for components exposed to frequent operation.
Other surface treatment options can be found on this page for reference.
